The store was established by Canadian entrepreneur Bob Lapointe with 25 staff members and it proved so popular that 38 more locations opened by 1970.
Many Australians would eat KFC as a rare treat and the menu looked different in the early days.
The store offered one piece of chicken and chips for 45 cents.
The menu also advertised 21 pieces of chicken for $5.20 and a large service of chips for 50 cents.
Today, 21 pieces of chicken costs about $37.95 and a large chips is $5.25.
The service centre was home to the KFC restaurant and a Pizza Hut, before the current owners bought the site in 2009 and turned it into a service station.
The site currently houses a 7-Eleven service station, Oporto drive-through, Cheesecake Shop, Piccolo Me cafe and a kebab shop.
